The real question is if we could ever figure out how nature is and works regardless of our minds or senses.The real "nature" of nature,so to speak. — dimosthenis9
I think the right view is to marvel at how it has been possible to extend semiosis to the degree that it has. Through metaphysics and science, humans have continued on to develop a level of reality modelling in which the world is seen from a "God's eye view". And not even the old fashioned kind of creating father-figure God that is just an idealised personification of a human observer, but a truly transcendent and coordinate free perspective which is pansemiotic, or the Universe's own view of itself (in some useful epistemic sense).
So once you reduce reality to a disembodied causal description - one based on symmetry and symmetry breaking – then you are claiming to talk about what is necessary and fundamental in regards to any kind of cosmic being whatsoever. You are seeing the deepest principles of nature and how it works – having stripped the view of all its superficial accidents to fix on its structural necessities.
So yeah. We are limited by our biology and sociology to being embodied observers of reality. But it is astonishing how well we can construct a useful notion of the perfectly disembodied observer contemplating the mathematical necessities of its own cosmic existence.
Celebrate the fact. No need to downplay the achievement.
Is it possible that we might need a new set of semiotics then as to go further,at least to difficult questions like in QM?And can we actually establish a new set of semiotics that could go even Maths further?I have no idea of what these semiotics could be or even if it is actually possible,if you ask me. — dimosthenis9
This is a tough question. First I would say that "real semiosis" is about an actual modelling relation in which a self is wanting to act on a world. There is some organism living and thriving in its environment. This means all the semiotic intelligence is being paid for by its functional results. It is a negentropic eddy in its environment that earns it keep by degrading entropy gradients. Baseline, life and mind exist because they use energy and increase entropy as the second law of thermodynamics demands.
Humans equipped with words and numbers just take this kind of "intelligence entrained to entropification" to a new level. We are now technological and civilisational organisms, growing at an exponential rate like bacterial spores on a Petrie dish. We produce enough waste heat to kill a planet.
Bad for us perhaps. But certainly this is following the logic of the cosmos. Semiosis exists because there is entropification to be done.
So what does semiosis mean once it rises above the worldly constraints of the second law? Science is still entrained to the second law when it is building human social machinery. Even our most sophisticated abstractions, like social media or bitcoin, have a considerable energy footprint. The electronics behind the information runs hot.
But would understanding the reality of the Big Bang be useful information in that entropic sense? Would we be able to create our own further Big Bangs – as was feared when they fired up the last supercollider? Or create simulated Big Bangs – as some claim our own Big Bang existence to be?
So yeah. Something changes as the modelling relation stops being between actual organisms entrained to the second law and instead this more lofty and disinterested pansemiotic view that may simply have no payback. Or in other words, becomes not even testable in terms of its conceivable practical effects.
This is a tricky area. But hey. It is not as if it is even a widely considered question. Semiosis is largely only understood in biology and sociology circles. It hasn't entered physics as a pansemiotic paradigm – although dissipative structure theory is paving the way.
So I guess you suggest that we need a new form of reasoning that would make us think different about what we observe.A new intelligence.A paradigm shift.Right?Is that possible then?And if yes how? Would that be a next step in human evolution? Leaving Homo behind? — dimosthenis9
Well there is a lot of what I think is silly talk about the Singularity and other thoughts about being uploaded to the cybersphere to become eternal and infinitely smart beings. That extrapolates the bad metaphysics of the Cartesian mind.
The self is seen as a disconnected and passive representer of reality, and so a data structure in a supercomputer ought to be able to replicate the same kind of informational state at far greater scale.
This is the model of the mind that semiotics explicitly rejects in talking about consciousness as an embodied or enactive modelling relation.
So my answer is that if you stop to think about Homo sapiens as a semiotic organism that serves the second law, then it becomes clear that we took our big evolutionary leaps first with the invention of language – quite a swift transition about 40,000 years ago once the grammatical structure was fully codified. And then about 400 years ago, we took another huge step with the codification of the "grammar" of our mathematical reality models. Differential equations in particular – the path to engineering and machinery – created a new modelling capacity.
That capacity would then have been not much of a big deal except we then also found we were sitting on buried reservoirs of fossil hydrocarbon. A planet's worth of coal and petroleum that the Universe would really want entropifying if anyone was smart enough to "eat" such toxic waste.
And Homo sapiens obliged. We became that sort of creature. And the Earth became that sort of planet.
So this is nature doing its thing. Finding ways to dissipate. Organisms armed with semiosis are nature's way to break down the barriers to dissipation. That is what intelligence is for in the cosmic scheme.
So yes. We can definitely use a deep understanding of nature to predict what lies in the future for us.
That explains why humans use so much of their smarts to deny and ignore climate change. We evolved to do a job. We can't just abandon it half done.
Too bad if this looks as dumb as bacteria reproducing furiously on a Petrie dish until their exponential growth collapses. Humans might have thought they were smart, but only discovered the reasons they came to view the world as they did – entrained to endless upward "progress" – much too late.
So the modern technological human self is in fact a quite unaware self in this regard. A social order was built around the cheap and limitless energy of fossil carbon. Modern society has the inbuilt urge to perpetuate that dissipative structure, and has never - in its short 400 years – had the reason or stimulus to build in a longer term energy transition plan.
But that gives you an answer to next possible levels of semiosis perhaps. We could have done something even just by instituting a simple mathematical trick like a carbon tax. We could have factored environmental costs into our economic projections. We could have regulated the markets so that information about the true ecological price of our consumption was something every market participant had clear in their minds.
The maths of these moves is completely trivial. No new semiotic technology required. But semiosis is about meaning creation. And building a new level of meaning into the system was what was required. The health of the planet should have been included in the cost of daily life.
So you do agree also that is possible no collapse at all taking place over there and we just think we spot one?Right? — dimosthenis9
No. My point is that "quantum weirdness" runs the gamut from maximally weird to not detectably weird at all under the mathematical framework provided by decoherence theory – the bolting of statistical mechanics onto quantum field theory.
So nature provides us with situations that range from minimally constrained to maximally constrained. Quantum mechanics simply reveals that nature runs this gamut. That is why an experimenter can arrange a measurement so that the observation is as nonlocal as possible, or as local as possible ... if the experimenter has the right machinery to shut the valve or open the valve.
This is important as life itself is based on molecular machinery – protein structures that can act as switches that turn "quantumness" on and off at the nanoscale level of quantum chemistry. Your existence is wholly dependent on respiratory chains that can take a hot electron and skip it down a set of precisely spaced receptors using quantum tunnelling, and so milk the electron of the energy needed to load up an ATP or other energy-carrying molecule.
Experimenters can turn knobs to tune quantum weirdness in and out of focus. Life is the semiotic trick of being able to do the same at the level needed to regulate organic chemistry. (Although we've only really known this for about 15 years.)
So I am saying that decoherence is a no collapse story. But only in the sense that it is instead a model of how nature runs the gamut between quantum coherence and quantum decoherence. Either a system has so many informational constraints that it approaches the classical limit, or it is so informationally unconstrained that it approaches the quantum limit.
And then on top of this labile spectrum, we can drop our own system of semiotic switches. We can control the degree of constraint – turn a knob from "collapsed" to "uncollapsed" and back again.
So nature has a richness of states. We make life simple by imposing a binary logic upon that. And even life itself exists because it invented codes that could operate a set of molecular switches to regulate decoherence. A respiratory chain could have its sequenece of iron-sulphur clusters spaced at exactly the right distance, down to angstroms, so a hot electron could do nothing else but skip down the fixed path provided to the waiting oxygen atom at the end of the line.
History's greatest feat of precision engineering, especially once you understand how much mitochondrial damage would be wreaked by a hot electron escaping the chain.
What could that training be? — dimosthenis9
It might help to start with a science like ecology where you need that kind of maths coupled to that kind of holistic situation. My story was that I was getting frustrated with the state of neurobiology and mind science – too reductionist. And so I looked around to see who really had a handle on holistic models of reality. It turned out to be theoretical biologists who were by then into hierarchy theory, systems science, cybernetics and - eventually - Peircean semiotics.
So you won't get given a training. You really have to go looking for it.
There is holism in physics as well. You have condensed matter physics, topological order, dissipative structure theory and holographic approaches all starting to come through strongly.
And even neurobiology has caught up with its "enactive turn". Friston's Bayesian brain is exactly the kind of semiotic model I'm talking about.
